ABSTRACT
Objective:To study the risk factors of Budd-Chiari syndrome (BCS) associated with hepatocellular carcinoma in patients who underwent endovascular recanalization.Methods:The data of 340 patients with BCS who underwent endovascular recanalization at the Affiliated Hospital of Xuzhou Medical University between January 2015 and June 2021 were retrospectively collected. Using propensity score matching, a total of 57 patients (40 males and 17 females) were enrolled into this study, with the age of (50.4±8.7) years. Patients were divided into the hepatocellular carcinoma group ( n=19) and the control group ( n=38) according to whether occurrence of hepatocellular carcinoma after cardovascular recanalization. Preoperative indicators including gender, age, BCS type, and model for end-stage liver disease (MELD) score, and postoperative indicators including alpha fetoprotein, intrahepatic nodule formation, vascular restenosis, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were compared between the two groups after propensity score matching. Multivariate logistic regression analysis was used to analyze the risk factors of BCS associated with after endovascular recanalization in these patients. Results:There were no significant differences in gender, age, BCS type, MELD score and other preoperative data between the two groups (all P>0.05). The proportions of patients with postoperative alpha fetoprotein>9.0 μg/L, AST>40 U/L, ALT>50 U/L, intrahepatic nodules and vascular restenosis after endovascular treatment in the hepatocellular carcinoma group were significantly higher than those in the control group (all P<0.05). Multivariate analysis showed postoperative alpha fetoprotein >9.0 μg/L ( OR=46.778, 95% CI: 3.310-661.140), AST>40 U/L ( OR=36.307, 95% CI: 1.317-1 001.009), intrahepatic nodule formation ( OR=66.254, 95% CI: 4.225-1 038.974) and vascular restenosis ( OR=16.276, 95% CI: 1.712-154.773) to have an increased risk of being associated with hepatocellular carcinoma in these BCS patients (all P<0.05). Conclusion:Postoperative alpha fetoprotein>9.0 μg/L, AST>40 U/L, intrahepatic nodule formation and vascular restenosis were independent risk factors of BCS associated with hepatocellular carcinoma in patients who underwent endovascular recanalization.
ABSTRACT
Objective:To study the efficacy, feasibility and safety of transjugular intrahepatic portosystemic shunt (TIPS) in treatment of recurrent portal hypertension after splenectomy and devascularization in patients presenting with upper gastrointestinal bleeding.Methods:Cirrhotic patients with recurrent portal hypertension after splenectomy and devascularization and presenting with upper gastrointestinal bleeding from August 2015 to December 2020 were studied. Thirty-nine patients were included in this study. There were 24 males and 15 females, with age of (51.56±9.08) years old. These patients were treated with TIPS by using the Viabahn stent. Intraoperative portal vein pressure, success operative rate, hemostasis rate after surgery, changes in hematological indicators and postoperative efficacy and complication rate were studied.Results:Thirty-eight of 39 patients successfully underwent TIPS shunt and 1 patient failed because of portal vein spongiosis. The success rate was 97.44%(38/39). Thirty-three patients underwent TIPS and variceal vein embolization, while 5 patients were treated with TIPS alone. Thirty-nine Viabahn stents with a diameter of 8 mm were implanted in 38 patients, of which 5 patients had the stent expanded to its nominal diameter of 8 mm. The remaining 33 patients (86.84%) had a shunt with a diameter of 6 mm. The hemostasis rate of postoperative gastrointestinal bleeding was 97.37% (37/38). The portal vein pressure and portal venous pressure gradient decreased from (31.28±6.24), (20.61±5.14) mmHg (1 mmHg=0.133 kPa) to (19.58±4.69), (9.24±3.07) mmHg respectively, the differences were significant (all P<0.001). All patients were followed-up for 3 to 36 months, with a median follow-up of 12 months. The postoperative rebleeding rate was 6.90% (2/29). The incidence of hepatic encephalopathy was 13.79% (4/29), and the incidence of shunt disorder was 13.79% (4/29). Conclusion:TIPS was safe, effective and feasible in treating patients with recurrent portal hypertension after splenectomy and devascularization presenting with upper gastrointestinal bleeding. Most patients obtained good clinical outcomes with a 6 mm diameter shunt.
ABSTRACT
Objective:To study the use of three-dimensional (3D) visualization in diagnosis and interventional treatment of patients with Budd-Chiari syndrome (BCS) presenting with inferior vena cava obstruction and dangerous collateral branches.Methods:The data of 28 patients with BCS presenting with inferior vena cava obstruction and dangerous collateral branches treated at the Affiliated Hospital of Xuzhou Medical University from September 2018 to January 2021 were retrospectively analyzed. There were 11 males and 17 females with a mean age of 49.0 years. Enhanced MR images of these 28 patients were used to build 3D visualization of inferior vena cava. Anteroposterior and left lateral digital subtraction angiography (DSA) of inferior vena cava were performed. The inferior vena cava of these patients was recanalized under guidance of 3D visualization, and patency of inferior vena cava was determined on follow up.Results:3D visualization of inferior vena cava was successfully constructed in all the 28 patients, and 51 dangerous collateral branches were displayed. One, 2, 3 and 4 dangerous collateral branches were found in 13, 8, 6 and 1 patients, respectively. The average angle between the preoperative planning puncture route and the long axis of the proximal end of inferior vena cava was 22.2°. The orifices and courses of the dangerous collaterals and the shape of inferior vena cava could be clearly displayed on 3D visualization in all the 28 patients (100.0%), which were significantly better than the 6 patients (21.4%) using DSA obtained in the anteroposterior and left lateral positions (χ 2=20.045, P<0.05). The inferior vena cava was successfully recanalized in all the 28 patients without complications. On follow up of these patients for 2 to 30 months (mean 18.4 months), the inferior vena cava was patent in 25 patients. Three patients developed inferior vena cava re-obstruction at 3, 4 and 14 months after interventional treatment, respectively. Conclusion:3D visualization was useful in the diagnosis and interventional treatment of patients with BCS presenting with inferior vena cava obstruction and dangerous collateral branches.
ABSTRACT
Objective:To investigate the changes of liver volume and liver function in patients with extensive hepatic vein occluded Budd-Chiari syndrome (BCS) treated with transjugular intrahepatic portosystem shunt (TIPS).Methods:The clinical data of 29 BCS patients from Affiliated Hospital of Xuzhou Medical University during March 2016 to June 2019 were retrospectively collected and analyzed. The BCS was caused by extensive hepatic vein occlusion and patients were treated with TIPS. Pre- and postoperative abdominal CT/MRI images were collected and analyzed, and hepatic volume was measured with 3D-reconstruction. The liver volume and liver function during before and post the surgery were also collected and analyzed with preoperative value.Results:Patients including 8 males and 21 females, aged (33.3±6.3) years, were enrolled in this study. TIPS was successfully performed in all patients, with a technical success rate 100%. No serious complications related to TIPS occurred. Patients were followed up for 12-33 months (median, 16 months). Compared with preoperative [(2 124.6±420.9) cm 3] , the hepatic volume of time points after operation [1 week: (1 926.3±372.3) cm 3; 3 months: (1 480.6±183.1) cm 3; 6 months: (1 461.9±153.0) cm 3; 12 months: (1 469.3±148.5) cm 3] were all significantly reduced, and the differences were statistically significant ( P<0.05). Compared with preoperative values, the hepatic function indexes at each time point after operation were significantly improved ( P<0.05). The complete remission rate of ascites was 96.4% (27/28), 100.0% (28/28) and 100.0% (28/28) at 3, 6 and 12 months, respectively. Conclusion:The extensive hepatic vein occlusive BCS patients were benefit from TIPS therapy. Six months after operation, the hepatic volume and the hepatic function returned to normal level.
ABSTRACT
Objective To investigate the application value of inferior vena cava venography in correlation between the subtypes of inferior vena cava obstruction and calcifications at the obstruction in Budd-Chiari syndrome (BCS).Methods The retrospective cross-sectional study was conducted.The clinical data of 41 patients with BCS who were admitted to the Affiliated Hospital of Xuzhou Medical University between January 2009 and December 2016 were collected.There were 29 males and 12 females,aged (53±10)years,with a range of 34-70 years.Forty-one BCS patients underwent computed tomography (CT),inferior vena cava CT venography and digital subtraction angiography (DSA) within 2 weeks.Balloon dilatation and (or) endovascular stent implantation of inferior vena cava were performed according to calcification morphology and location of the inferior vena cava obstruction detected by DSA.Observation indicators:(1) calcifications of inferior vena cava obstruction;(2) intraoperative situations of interventional therapy;(3) correlation between the subtypes of inferior vena cava obstruction and calcifications at the obstruction;(4)follow-up and survival situations.Follow-up using outpatient examination of inferior vena cava venography was performed at 3,6,12,24,36,48 months postoperatively to detect postoperative clinical manifestations,complications and survival situations up to December 2018.Measurement data with normal distribution were represented as Mean±SD.Count data were represented as absolute number and comparison between groups was analyzed using the chi-square test.The likelihood ratio test was used to analyze the correlation between the subtypes of inferior vena cava obstruction and calcifications at the obstruction.The degree of correlation was detected by Cramer's V contingency coefficient.Results (1)Calcifications of inferior vena cava obstruction:of 41 patients,17 had no calcification at the inferior vena cava obstruction and 24 had calcifications at the obstruction.Calcification location in 24 patients:there were 17,4 and 3 patients with proximal,distal,both proximal and distal calcifications at the inferior vena cava obstruction,respectively.Calcification morphology:punctate and irregular calcifications were detected in 20 and 4 patients,respectively.Calcification distribution:20,3 and 1 patients had scattered,cluster and diffuse distribution,respectively.(2) Intraoperative situations of interventional therapy:of 41 patients,21 underwent balloon dilatation and 20 underwent balloon dilatation combined with endovascular stent implantation.Two patients were detected hematoma at the puncture site of right femoral vein and treated using pressure dressing.One patient encountered rupture of balloon due to diffuse calcifications at the inferior vena cava obstruction and was improved after continual replace of balloon for 3 times.One patient had pulmonary embolism caused by detachment of the thrombosis at the distal obstruction during the balloon dilatation and was given anticoagulation therapy combined with thrombolytic therapy using large-dose of urokinase.The other 37 patients underwent successful interventional therapy without exceptional circumstances.(3) Correlation between the subtypes of inferior vena cava obstruction and calcifications at the obstruction:of 24 patients with calcifications at the inferior vena cava obstruction,13 had membrane obstruction,7 had segmental obstruction and 4 had fenestrated membrane obstruction.Of 17 patients without calcifications at the inferior vena cava obstruction,3 had membrane obstruction,13 had segmental obstruction and 1 had fenestrated membrane obstruction.The likelihood ratio test showed that the subtypes of inferior vena cava obstruction were associated with calcifications at the obstruction (x2=9.293,P＜0.05),with the correlation coefficient V as 0.466.Further analysis showed a correlation between membrane obstruction of inferior vena cava and calcifications at the inferior vena cava obstruction (x2=8.121,P＜0.05),no correlation between segmental obstruction and calcifications at the inferior vena cava obstruction,also no correlation between fenestrated membrane obstruction and calcifications at the inferior vena cava obstruction (x2=3.395,0.004,P＞0.05).(4) Follow-up and survival situations:41 patients were followed up for 24.0-48.0 months,with a median time of 37.1 months.Postoperative ultrasound showed smooth backflow in the inferior vena cava,different degree of improvements in the lower limb swelling and varicosity in 38 patients.Embolisms in the inferior vena cava obstruction remained existent in 3 patients,1 of whom showed significant decreasing of embolisms.There were 2 patients found restenosis and undergoing endovascular stent implantation.All the 41 patients survived.Conclusions The subtypes of inferior vena cava obstruction are associated with calcifications at the obstruction in BCS.Inferior vena cava venography evaluating calcifications at the inferior vena cava obstruction in BCS can be helpful for diagnosing the subtypes of inferior vena cava obstruction and guiding its interventional therapy.
ABSTRACT
Ohjective To evaluate the safety and efficacy of transjugular intrahepatic portosystemic shunt (TIPS) in the treatment of sinusoidal obstruction syndrome (SOS) caused by gynura segetum.Methods The clinical data of 9 patients with SOS caused by gynura segetum (5 males and 4 females) who underwent TIPS were retrospectively analyzed from February 2017 to June 2018.The Child-Pugh scores were (9.5 ± 1.3) and the MELD scores were (12.5 ± 5.0).The success rates,complications and follow-up results were evaluated.Results TIPS was performed successfully in all the 9 patients.The portal venous pressure gradient dropped from (22.4 ± 2.7) mmHg to (10.4 ± 3.2) mmHg (P ＜ 0.05).There was no complication such as abdominal hemorrhage and biliary peritonitis.Nine patients were followed-up for 1 ～17months,mean 7.8 ± 6.0 months.One month after treatment,the Child-Pugh scores were (7.1 ± 1.8),compared with that of the preoperative scores,the difference was statistically significant (P ＜ 0.05).The MELD scores were (5.3 ± 4.6),compared with that of the preoperative scores,the difference was also statistically significant (P ＜ 0.05).At the end point of the follow-up,color Doppler ultrasound and portal CTA showed that the TIPS shunt was patent and hepatic congestion was relieved in all the 9 patients.All patients were alive.Conclusion TIPS was a safe and efficacious treatment for SOS caused by gynura segetum.
ABSTRACT
Objective To analyze the application of three-dimensional visualization in interventional treatment of Budd-Chiari syndrome (BCS) with the hepatic vein occlusion type.Methods A retrospective study was conducted on 15 patients with BCS of the hepatic vein occlusion type who were admitted to the Affiliated Hospital of Xuzhou Medical University from January 2017 to June 2018.The study included 8 males and 7 females with a mean age of (36.7±14.4) years.All patients were examined with MRI enhanced scanning and the original MRI data of the DICOM format were extracted.The digital data were then extracted and reconstructed by the Mimics software to obtain a three-dimensional visualization model.The hepatic vein was recanalized under the guidance of the three-dimensional visualization model.Results The three-dimensional visualization model was successfully constructed.Of all the 15 three-dimensional visualization models,right hepatic vein ostial stenosis occurred in 4 patients and occlusion in 11 patients.The middle hepatic vein and the left hepatic vein formed a common trunk in 15 patients,and ostial stenosis and occlusion of the common trunk occurred in 3 and 12 patients,respectively.Communicating branches between the right and middle hepatic veins occurred in 6 patients.Accessory hepatic veins occurred in 3 of 15 patients,and the accessory hepatic vein ostium was stenosed in 3 patients.Communicating branches between the accessory hepatic vein and the right hepatic vein occurred in 2 patients,and communicating branches between the accessory hepatic vein and the middle hepatic vein occurred in 1 patient.All patients were treated successfully with interventional treatment without any complications.One,2,and 3 hepatic veins were recanalized in 7,5 and 3 patients,respectively.Conclusion The three-dimensional visualization was valuable in displaying the location,pattern and collateral vessels of the hepatic veins in BCS patients with the hepatic vein occlusion type.It was helpful for accurate preoperative assessment and to make individualized interventional treatment plans.
ABSTRACT
Objective To study the safety and efficacy of accessory hepatic vein (AHV) stenting to treat primary Budd-Chiari syndrome (BCS).Methods The clinical data of 20 BCS patients with AHV ostial stenosis or occlusion were retrospectively analyzed.These 20 patients underwent balloon dilation and AHV stenting.Thirteen patients underwent AHV stenting via the right jugular vein approach,5 patients via the right femoral vein approach,and 2 patients via the percutaneous transhepatic combined with the right femoral vein approach.On follow-up,patency of the AHV stent was evaluated by color Doppler ultrasound.The cumulative primary and secondary patency rates were assessed with the Kaplan-Meier curves.Results AHV stenting was successful in 20 patients.Angiography showed that the AHV was patent after stenting.The mean pressure gradient between the AHV and the inferior vena cava reduced from (19.2 ± 4.8) cmH2O (1 cmH2O =0.098 kPa) before treatment to (4.5 ± 1.9) cmH2O after treatment (t =7.119,P ＜ 0.01).During the procedure,rupture of the AHV caused by balloon dilation occurred in one patient.This was treated successfully by a covered stent placement.On follow-up from 1 to 80 months [(32.1 ±27.4) months]after treatment for the 20 patients,re-stenosis of the AHV were found in 5 patients.They were treated successfully with re-dilation.The cumulative 1-,3-,and 5-year primary patency rates were 100％,85.1％ and 74.5％,respectively.The cumulative 1-,3-,and 5-year secondary patency rates were 100％,90.9％ and 90.9％,respectively.One patient died of hepatic failure 3 years after the treatment.Conclusion AHV stenting was a safe and efficacious treatment for BCS and it provided good mid-and long-term results.
ABSTRACT
Objective To explore the endovascular treatment of Budd-Chiari syndrome (BCS) in young child. Methods The clinical data of one young child diagnosed with BCS and treated with endovascular therapy were retrospectively analyzed. Results The 23-month-old female suffered from repeated abdominal distension for 3 months and was diagnosed with BCS by vascular ultrasound Doppler and magnetic resonance examination.

Then the occluded blood vessels resumed blood stream, urine output increased, and abdominal distension was significant relieved. Conclusions In young children, BCS is rare, the condition is complex, and endovascular therapy is effective.
ABSTRACT
Objective To evaluate the safety and efficacy of Viabahn covered stent in treatment of hepatic artery pseudoaneurysm (HAPA) caused by surgery.Methods Clinical data of 7 patients with postoperative massive intra-abdominal hemorrhage and diagnosed as HAPA with emergency angiography were collected from November 2015 to May 2016.All the patients underwent Viabahn covered stent implantation.Perioperative and postoperative clinical data of the patients were recorded,and with 1-month follow-up.Results All the 7 cases were diagnosed as extrahepatic HAPA and successfully completed Viabahn covered stent procedure,and curative rate was up to 100％.One case experienced transient vasospasm in the hepatic artery proximal to the stent.All the patients repeated hepatic artery CT angiography scans one week after surgery,with no evidence of bleeding.With 1-month follow-up,all the patients were in stable conditions.Conclusion Viabahn covered stent is minimally invasive,simple and effective interventional approach for HAPA.
ABSTRACT
Objective To evaluate the clinical effect of reduced glutathione in protecting the liver function for patients with hepatocellular carcinoma (HCC) after receiving international therapy.Methods The clinical data of 110 HCC patients,who were admitted to authors' hospital during the period from January 2010 to June 2013,were retrospectively analyzed.According to the random number table method the patients were divided into the control group (n=50) and the treatment group (n=60),and transcatheter arterial chemoembolzation (TACE) and transcatheter arterial infusion (TAI) were carried out in all patients.After the treatment,intravenous infusion of 2.0 g vitamin C,0.2 g vitamin B6,2.0 g inosine,and 250 ml branched chain amino acid was employed per day for one week for the patients of both groups,and additional intravenous dripping of 1.8 g reduced glutathione (added in 250 ml of 5％ glucose solution) was adopted for the patients of the treatment group.Various liver function indexes were tested before and one week after the treatment,the results were compared between the two groups.Results Before the treatment,no obvious differences in the hepatic functions and in the clinical condition existed between the two groups.One week after the treatment,in both groups the aminotransferase (ALT and AST) and total bilirubin (TBIL) were significantly increased when compared with the preoperative data (P＜0.05),while the serum pre-albumin (PA) was remarkably decreased when compared with the preoperative data (P＜0.05);these changes of various indexes in the treatment group were apparently better than those in the control group (P＜0.05).Conclusion The use of reduced glutathione can effectively relieve the liver function damage caused by interventional therapy in HCC patients,therefore,reduced glutathione has a very good clinical application value.
ABSTRACT
Objective To study the intra-and extra-hepatic collateral pathways in various types of Budd-Chiari syndrome (BCS) using liver acceleration volume acquisition (LAVA) enhanced MRI.Methods The clinical data and imaging findings of 240 patients with BCS were collected and analyzed.The types of BCS confirmed by DSA.Intra-and extra-hepatic collateral pathways were studied using LAVA enhanced MRI with a 3.0T scanner.Correlations of the intra-/extra-hepatic collateral pathways with the types of BCS were analyzed using the Chi-square test.Then,the degrees of correlation were calculated by the Cramet correction coefficient of contingency.Results Among the 240 patients,DSA confirmed 60 patients to have hepatic vein occlusion,39 patients to have inferior vena cava occlusion and 141 patients to have both hepatic vein and inferior vena cava occlusion.MRI demonstrated dilated accessory hepatic veins in 157 patients,intra-hepatic communicating branches in 69 patients,inferior phrenic veins in 43 patients,superficial epigastric veins in 135 patients,umbilical veins in 94 patients and hemiazygos/azygos veins in 195 patients.Accessory hepatic veins and hemiazygos/azygos veins as collateral pathways were associated with the types of BCS (x2 =30.239,P ＜ 0.05;x2 =51.295,P ＜ 0.05,respectively).The degrees of correction were 0.355 and 0.462,respectively.Accessory hepatic veins as collateral pathways were most common in the mix type,accounting for 79.4％.Hemiazygos/azygos veins were most common in the inferior vena cava occlusion type and the mix type,accounting for 92.3％ and 91.5 ％,respectively.Conclusions Accessory hepatic veins and hemiazygos/azygos veins as collateral pathways were associated with the types of BCS,while the intra-hepatic communicating branches,inferior phrenic veins,superficial epigastric veins and umbilical veins were not correlated with the types of BCS.LAVA may help to diagnose and determine the best choice of treatment for the various types of BCS.
ABSTRACT
Objective To investigate the value of guide-wire loop in interventional therapy of patients with Budd-Chiari syndrome with hepatic vein obstruction.Methods A retrospective study was conducted on 25 patients with Budd-Chiari syndrome (BCS) with hepatic vein obstruction treated from May 2011 to August 2014.The technique of guide-wire loop was used in these patients.The pressure of the hepatic vein was measured before and after treatment.The difference in the pressure was analyzed by the t test.Results All the patients were treated successfully using guide-wire loop angioplasty.No complications of bleeding,pericardial tamponade and liver capsule hemorrhage were observed.After treatment,the pressure of the hepatic vein reduced from (48.3± 8.0) cmH2O to (20.9 ± 3.8) cmH2O (t =26.82,P ＜ 0.05);The symptoms and physical signs of the patients were relieved or disappeared.BCS-related symptoms reappeared on follow-up in 4 patients,2 were treated by balloon dilation successfully.1 patient was treated with transjugular intrahepatic portosystemic shunt (TIPS) because of decompensated liver cirrhosis.1 patient with ankylosing spondylitis had treatment failure and the symptoms relapsed for the third time.Conclusion The technique of guide-wire loop in interventional therapy of patients with Budd-Chiari syndrome with hepatic vein obstruction is safe and effective,and it can improve the overall success rate of treatment.
ABSTRACT
Objective To evaluate the changes in the number and activities of endothelial progenitor cells (EPCs) from peripheral blood in patients with primary Budd-Chiari syndrome (BCS),and to explore the possible mechanisms of BCS.Methods Eighty-two patients with BCS and 20 healthy subjects used as controls were recruited for this study.The EPCs from peripheral blood were counted by flow cytometry for CD34,CDl33 and KDR for positivity.The peripheral blood mononuclear cells were isolated by density gradient centrifugation and cultured for 7 days.Characterization of EPCs as adherent cells was done using double staining of FITC-UEA-1 and DiI-Ac-LDL binding.The proliferation,adhesion and migration activities were assayed by MTT chromatometry,adhesion activity assay and Transwell assay,respectively.Results EPCs (CD34+/CD133 +/KDR+) were depleted in the BCS patients as compared to the healthy controls [(0.020 ± 0.005) ％ vs (0.038 ± 0.007) ％].The proliferation activities (0.20 ± 0.04 vs 0.58 ± 0.07),adhesion activities (15.8 ± 1.6 vs 35.0 ± 2.5) and migration activities (16.1 ± 1.7 vs 23.9 ± 2.6) were significantly lower in the BCS group than the control group (P ＜ 0.05).Conclusion EPCs from the peripheral blood in patients with BCS exhibited reduced numbers and impaired proliferation,adhesion and migration activity,which may be the key factors for vasculopathy formation in primary BCS patients.
ABSTRACT
<p><b>OBJECTIVE</b>To determine whether there are differences in both the right hepatic vein (RHV) morphology and the size of the angle between the inferior vena cava and the RHV in patients with membranous obstruction of the inferior vena cava (MOVC),in healthy individuals and in patients with cinhosis (HLC), in order to help guide development of an effective interventional treatment program.</p><p><b>METHODS</b>Consecutive patients (n=248) were divided into the following three groups: group A (control; n=94), group B (MOVC patients; n=68), group C (HLC patients; n=86). The angle between the hepatic vein and inferior vena cava was measured and defined as the T value. The morphology of the RHV was classified as N, U, or I. The difference of the constituent ratio was compared among the three groups for the T value and the angle type.Measurement data was calculated as x ± s,and groups were compared using one-way ANOVA; count data was calculated as relative number, and groups were compared using the chi-square test.</p><p><b>RESULTS</b>The average T value of group B was significantly higher than that of group A (56.1 ± 13.7 vs. 49.3 ± 7.8, P=0.010) and of group C (vs. 51.5 ± 10.0, P < 0.001); the difference was statistically significant (F=8.750, P < 0.001), but there was no significant difference between the groups A and C.N-type proportion of B group was 48.5% (33/68), greater than that of group A(16.0%,15/94) and C (16.3%, 14/86), x² = 20.1, x² =18.6.U-type proportion of B group was 11.8% (8/68), smaller than that of groups A (28.7%,27/94) and C (37.2%, 32/86), 2 2 = 6.70, x² =12.8, and the differences were statistically significant (P < 0.01). For groups A and C, the N and U types were not significantly different.</p><p><b>CONCLUSION</b>The angle between the RHV and the inferior vena cava in MOVC patients is morphologically different from that in healthy humans, with the angle value in MOVC patients being slightly larger. However, this difference is irrelevant to cirrhosis.</p>

Objective To investigated the serum level of carcinoma antigen 125 (CA-125) and its clinical significance in patients with Budd-Chiari syndrome.Methods We reviewed medical records and laboratory tests of patients with BCS first diagnosed in our hospital between August 2011 and April 2013.235 patients were included as experiment group,while 120 healthy adult volunteers were randomly selected as control group.The serum level of CA-125 were detected by electrochemilumescence immunization assay in this single-center retrospective control study.Results The average serum level of CA-125 in experiment group is higher than that of control group [(147.9 ±246.6) kU/L vs (16.0 ±7.2) kU/L,P ＜0.001].In experiment group,the relative coefficient for serum CA-125 with ascites,alanine aminotransferase,aspartate aminotransferase,albumin and Rotterdam BCS scores was 0.79,0.45,0.29,-0.393 and 0.71,respec tively,P ＜0.001.As of October 2013,we found that the 68 BCS patients with serum CA-125 level 5-fold higher than the upper limit of normal (＞ 175 kU/L) presented much lower survival rates and asymptomatic survival rates than the rest 167 BCS patients after intervention therapy:(95.6％ and 79.8％) vs (98.8％ and 92.0％),P ＜ 0.05.Conclusions The serum level of CA-125 in BCS patients have positive correlation with ascites volume,liver injury degree and Rotterdam BCS scores.Serum CA-125 evaluation appears to be a valuable examination option in BCS as CA-125 levels negatively correlate with worse prognosis,thus could be applied as an efficient tool for prognostication.
ABSTRACT
Objective To explore the therapeutic efficacy of endovascular embolization for the treatment of tiny intracranial aneurysms (≤3.0 mm) and to discuss its technical skill. Methods During the period from Dec. 2010 to July 2013, a total of 12 patients with tiny intracranial aneurysms (≤3.0 mm) were admitted to authors’ hospital to receive endovascular embolization therapy. Of the 12 patients, narrow-necked aneurysm (neck-to-body ratio ≤0.5) was seen in 7 and embolization with coils only was carried out, while wide-necked aneurysm (neck-to-body ratio > 0.5) was seen in 5 and stent-assisted coils embolization was adopted. Based on Raymond grading standard, the immediate therapeutic results were evaluated, and the procedure-related complications were recorded. Thirty days after the treatment , GOS grade was used to assess the results. Follow-up evaluation with angiography or through call was conducted. Results Successful embolization of the aneurysm was obtained in all the 12 aneurysms , with a success rate of 100%. Angiography performed immediately after the treatment showed that complete embolization was achieved in 8 aneurysms (66.7%) and residual aneurysm cavity was seen in 4 aneurysms (33.3%). GOS grading indicated that 12 cases belonged to grade V. The 12 patients were followed up for 1 - 12 months through telephone , and no re-bleeding occurred. Conclusion For the treatment of tiny intracranial aneurysms (≤ 3.0 mm), endovascular embolization is feasible although its safety and efficacy need to be further observed.

Objective To study the clinical features and prognosis of patients with primary BuddChiari syndrome (BCS) caused by hepatic vein thrombosis.Method 16 patients with primary BCS caused by hepatic vein thrombosis treated in our hospital between June 2010 to December 2012 were used as the study group while 132 patients with primary BCS caused by other causes were used as the control group.A retrospective study was then employed to analyze the clinical data of the two groups of patients during hospitalization and on follow-up.The study was censored in June 2013.The median follow-up was 24 months (range,6 months to 36 months).The difference in quantitative data between the 2 groups were analyzed using the independent-samples t test and the Wilcoxon W rank sum test,and the difference in qualitative data were analyzed using the Chi-square test and the Fisher's exact test.The survival rates and recurrence rates were calculated using the Kaplan-Meier method.Result The study group was significantly lower than the control group in age,duration of symptoms,albumin level,diameter of spleen and survival rate,but it was significantly higher in the proportion of patients with ascites,average hospitalization time,alanine transaminase,aspartate aminotransferase,total bilirubin,carbohydrate antigen-125 and recurrence rate after percutaneous transluminal angioplasty.The differences were significant (P ＜ 0.05).The Rotterdam BCS prognosis grades of the study group were:9 patients grade Ⅱ and 7 patients grade Ⅲ.In the control group,there were 65 patients with grade Ⅰ,51 patients with grade Ⅱ,and 16 patients with grade Ⅲ.The prognosis grade of the study group was significantly higher than the control group (P ＜ 0.05).Conclusion When compared to the patients with BCS due to other causes,patients with BCS caused by hepatic vein thrombosis were more common in the young,most of them were diagnosed in the acute period,they had worse clinical outcomes and had more severe clinical symptoms and liver damage.
ABSTRACT
Objective To evaluate the safety and efficacy of interventional treatment of occlusion of the entire inferior vena cava (IVC).Methods The clinical data of 6 patients with entire IVC occlusion were analyzed retrospectively.All patients were diagnosed by color Doppler ultrasound and DSA.Venography was performed under local anesthesia via internal jugular vein and femoral vein approach.The occlusion of IVC and hepatic vein were treated with balloon dilatation and/or stent placement.Follow-up examination with color Doppler ultrasound was taken 1,3,6,12 months after treatment and annually thereafter to assess the patency of IVC and hepatic vein.The pressure gradient of hepatic vein-right atrium and IVC-right atrium before and after interventional treatment were compared with paired t test.Results In 5 cases,both IVC and 1 hepatic vein were recanalized successfully.In 1 case,recanalization of IVC failed,but the right hepatic vein was recanalized successfully.The mean pressure gradient of hepatic vein-right atrium decreased from (23.2 ± 2.0) cmH2O (1 cmH2O =0.098 kPa) before treatment to (8.7 ± 3.2) cmH2O after treatment in 6 cases (t =21.6,P ＜ 0.05).The mean pressure gradient of IVC-right atrium decreased from (26.6 ± 2.7) cmH2O before treatment to (9.4 ± 1.1) cmH2O after treatment (t =16.1,P ＜ 0.05).Abdominal pains occurred in 3 patients after stent implantation which disappeared in 24 hours.No other complications such as bleeding and death occurred.During a mean follow-up of(42 ± 27)months (16 to 90 months),hepatic vein patency was maintained in 6 cases and IVC patency was maintained in 5 cases.Conclusion Interventional treatment of occlusion of the entire IVC is a safe and effective method.
